I have a 14 foot portabote that works great for us. But we like to fish and explore with it. Its big comfortable to sit in while fishing and I don't have to worry about the kids putting a hook in it. I do love the looks and idea of the PT 11 nesting. Sailing magazine has a Bob Perry review on it this month. Might have to build one when the kids out grow their little 8 foot sailing dinghy.
